This article is based on an official press release from GE Aerospace.
GE Aerospace announced on May 19, 2026, that it secured a U.S. Air-Forces contract to complete the preliminary design review (PDR) for its GE426 engine. According to the company’s press release, this new propulsion system is tailored specifically for the military’s medium-thrust-class Autonomous Collaborative Platform (ACP) initiative.
The ACP program, spearheaded by the Air Force Research Laboratory, aims to field uncrewed, AI-piloted combat aircraft designed to operate alongside crewed fighters. These autonomous platforms are intended to take on high-risk missions, carry munitions, conduct surveillance, and perform electronic warfare in highly contested environments.
While financial terms of the agreement were not disclosed in the announcement, the contract represents a critical step in the competitive landscape of next-generation military propulsion. We note that this development highlights the Pentagon’s ongoing push to rapidly scale its autonomous fleet capabilities through diversified supplier networks.
Contract Details and the GE426 Engine
Advancing to Preliminary Design Review
Under the newly announced contract, GE Aerospace will advance the GE426 prototype through the PDR phase. The company stated that this stage will focus on refining system capabilities, ensuring production readiness, and optimizing cost efficiency to meet Air Force requirements for the medium-thrust fleet.
The agreement was facilitated through an Other Transaction Authority (OTA) Project Agreement by SOSSEC, Inc., supporting the Air Force Propulsion Directorate under the Propulsion Consortium Initiative 2.0, according to industry research data. This milestone follows the engine’s successful concept design review in August 2025, which validated its core architecture.
Purpose-Built for Autonomous Combat
The GE426 is specifically engineered for the medium-thrust-class ACP mission. Unlike smaller, attritable drones, platforms utilizing the GE426 are expected to be larger and more capable. GE Aerospace emphasized in its release that the design prioritizes high performance alongside affordability and manufacturability at scale.
Expanding the Propulsion Portfolio
A Multi-Tiered Approach
The U.S. military is deliberately cultivating multiple engine suppliers to support various thrust classes and mission profiles within the ACP program. In February 2026, the Air Force awarded development contracts to several industry teams, including Beehive Industries, Honeywell, Pratt & Whitney, and a joint GE Aerospace-Kratos team, to mature engine designs for Collaborative Combat Aircraft (CCA) Increment 2.
The GE426 occupies a distinct thrust class within GE’s expanding portfolio of small, cost-effective defense engines. This lineup also features the GEK800 and the GEK1500, the latter producing approximately 1,500 pounds of thrust in partnership with Kratos Defense & Security Solutions.
“We’ve proven we can rapidly move from concept to engine demonstration with the GEK800,” stated Steve “Doogie” Russell, Vice President and General Manager of Edison Works at GE Aerospace, in the press release. He added that the current focus is applying that same process to the GE426 to deliver necessary performance and affordability.
Strategic Implications
AirPro News analysis
The advancement of the GE426 engine underscores a fundamental shift in modern aerial warfare strategy. By prioritizing human-machine teaming, the U.S. Air Force is attempting to multiply its combat mass affordably while keeping human pilots out of the most severe threat zones.
A central challenge for the ACP program is the industrial base’s ability to produce engines at scale and at a significantly lower cost than traditional crewed fighter engines. GE Aerospace’s explicit focus on “producibility” signals that advanced manufacturing techniques will be just as critical as aerodynamic performance in winning future defense contracts. We view this contract as a strong indicator of government confidence in GE’s ability to transition next-generation military technology from concept to scalable production.

Bell Textron Begins AH-1Z Viper Production for Nigerian Air Force
Bell Textron starts production on 12 AH-1Z Viper helicopters for Nigeria under a $455M contract, with delivery projected for early 2029.

Bell Textron Inc. has officially commenced production on the first of 12 Bell AH-1Z Viper attack helicopters for the Nigerian Air Force (NAF), marking the milestone with a beam-signing ceremony at its Amarillo Assembly Center in Texas on September 16, 2026.
The manufacturing milestone advances a Foreign Military Sales (FMS) agreement designed to bolster Nigeria’s counterterrorism and counterinsurgency operations. According to a press release issued by Bell, the initial structural beam will carry the signatures of the teams involved in bringing the aircraft to the production line.
Advancing the Nigerian AH-1Z Viper program
The U.S. State Department initially approved the possible FMS package for Nigeria in April 2022, with an estimated total value of $997 million covering the 12 helicopters, associated weapons, training, and support equipment. In March 2024, the U.S. Naval Air Systems Command (NAVAIR) awarded Bell Textron a $455 million firm-fixed-price contract specifically for the production and delivery of the aircraft.
Integration and support planning have been underway for several years. In June 2025, the U.S. Marine Corps H-1 Light/Attack Helicopter Program Office hosted a Program Management Review with NAF officials in California. A U.S. government delegation subsequently met with NAF authorities in Abuja, Nigeria, in February 2026 to finalize the comprehensive Program and Support Plan, ensuring facilities and logistics are prepared for the fleet’s arrival.
NAF Spokesperson Air Commodore Ehimen Ejodame stated that the platform will play an important role in strengthening the nation’s security operations and protecting its citizens.
“We are pleased with the Viper’s advanced capabilities and interoperability and look forward to its induction as a key platform in our attack helicopter fleet,” Ejodame said.
Production timelines and strategic context
Bell projects that aircraft production will be completed in early 2029. This represents an adjustment from the original March 2024 U.S. Department of Defense (DoD) contract announcement, which anticipated work completion by July 2028.
Scott Sims, Bell H-1 Program Director, noted the collaborative effort required to reach the manufacturing phase and the dedication of the employees supporting the international partner.
“The beam of the first production Viper for Nigeria will forever carry the names, hopes, and commitment of those who brought this aircraft to life,” Sims said.
The helicopter procurement aligns with ongoing bilateral security cooperation between the United States and Nigeria. In September 2026, the U.S. Africa Command facilitated the delivery of additional military equipment to Nigeria via a U.S. Air Force Boeing C-17 Globemaster III, underscoring the active counterterrorism partnership between the two nations.
AirPro News analysis
The shift in the projected completion date from July 2028 to early 2029 highlights the complex realities of international military aircraft procurement. While the initial contract award provided a baseline timeline, the extensive bilateral meetings throughout 2025 and 2026 suggest that establishing the necessary maintenance, training, and logistical infrastructure in Nigeria is as critical to the program’s success as the manufacturing process itself. We view the Bell AH-1Z Viper acquisition as a significant capability leap for the NAF, requiring substantial groundwork before the airframes can be effectively integrated into active service.

Germany Unveils First F-35A Lightning II in Fort Worth
Germany’s first F-35A rolled out Sept. 18, 2026, under an $8.8B deal for 35 jets to replace the Tornado and fulfill NATO nuclear sharing.

Lockheed Martin Corporation and the German government officially unveiled Germany’s first F-35A Lightning II during a rollout ceremony in Fort Worth, Texas, on September 18, 2026. The milestone marks the beginning of a fleet transition that will see the fifth-generation fighter replace the aging Panavia Tornado Military-Aircraft and assume the country’s North Atlantic Treaty Organization (NATO) nuclear sharing mission.
The rollout follows the aircraft’s initial flight on September 8, 2026, and stems from an $8.8 billion Contracts signed in 2022 for 35 airframes. In a press release issued by Lockheed Martin, German Minister of Defense Boris Pistorius described the event as the start of a new era for the German Air Force, calling the F-35A the world’s most advanced combat aircraft.
Training and delivery timeline
The first eight German F-35A Lightning II jets are scheduled to transfer to Ebbing Air National Guard Base in Arkansas in the fall of 2026. This initial cadre will support pilot and maintenance Training in the United States before the fleet begins its transition to Europe.
According to defense intelligence provider Janes, the first aircraft, bearing serial number 35+01, will eventually be stationed at Büchel Air Base in Germany. Lockheed Martin projects the first jets will arrive on German soil in late 2027. The German Air Force targets 2029 to declare full operational capability for the fleet.
Lieutenant General Holger Neumann, Chief of the German Air and Space Force, stated that the acquisition will fundamentally alter the service’s operational approach.
“With the F-35, the German Air and Space Force is receiving a modern, proven and highly capable 5th Generation fighter jet. It will not only bring significant changes in our Air and Space Force but will also influence how we think, command and fight,” Neumann said.
Strategic implications and NATO interoperability
The procurement aligns Germany with a growing user base of European nations operating the F-35 platform. Lockheed Martin reports that 1,355 F-35 aircraft are currently operational globally across 42 bases. OJ Sanchez, president of Lockheed Martin Aeronautics, emphasized the platform’s role as a strategic capability that enables allied forces to operate cohesively and adapt to emerging threats.
The transition is critical for Germany’s continued participation in NATO’s nuclear sharing agreement. The Panavia Tornado fleet, which has been in service since the 1980s, currently fulfills this requirement. Dan Zimmerman, performing the duties of the US Deputy Undersecretary for Acquisition and Sustainment, told Breaking Defense that Germany’s procurement reinforces a shared vision for defense in the European theater.
AirPro News analysis
The successful rollout of the first German F-35A Lightning II arrives at a pivotal moment for European defense procurement. Earlier in 2026, the Franco-German-Spanish sixth-generation Future Combat Air System (FCAS) program collapsed. We view this development as a primary catalyst for ongoing discussions regarding a potential follow-on Orders for additional F-35A aircraft by the German government. With the FCAS timeline now dissolved, Berlin must secure long-term air superiority and nuclear deterrence capabilities through established platforms, making an expansion of the 35-aircraft program of record highly probable.

Auriga Space Hermes Field Test Achieves Mach 1 in Mojave
Auriga Space completed the first in-field launch of its Hermes electromagnetic platform in the Mojave Desert, exceeding Mach 1.

Aerospace and defense startup Auriga Space completed the first in-field launch of its Hermes containerized electromagnetic platform in the Mojave Desert on August 25, 2026, achieving projectile speeds exceeding Mach 1.
The test demonstrates the viability of the company’s proprietary linear electric motor and magnetic levitation technology outside laboratory conditions. According to company statements, Auriga Space is developing these systems to provide a propellant-free alternative to traditional solid rocket motors for defense applications, hypersonic testing, and dedicated space access.
Transitioning electromagnetic launch to the field
The Hermes system is designed as a mobile counter-unmanned aerial systems (counter-UAS) platform housed entirely within a 10-foot shipping container. During the August 25 test, the system operated on internal battery power recharged by solar panels.
Auriga Space Founder and CEO Winnie Lai stated the test met expectations with multiple repeatable supersonic launches.
“For the first time, we took Hermes out of the lab and deployed it where it will actually be used: on a dirt road, away from existing infrastructure, in real weather,” Lai said in a press release.
Lai also noted the system’s payload flexibility, stating it can accommodate different types of projectiles and effectors. This capability aligns with the company’s July 2026 partnership with the U.S. Army Combat Capabilities Development Command Armaments Center (DEVCOM AC) to operationalize electromagnetic launch technology for drone defense.
Scaling from hypersonic testing to orbital launch
Beyond the Hermes platform, the Garden Grove, California-based company is developing three other distinct product lines: Prometheus, Thor, and Zeus.
Prometheus serves as a lab-scale hypervelocity track, while Thor is designed as an outdoor full-scale hypersonic test solution. On July 1, 2026, Auriga Space launched its hypersonic materials testing capability with Axiom Materials as a pilot customer. Lai noted that the hypersonic testing community has long needed better ground-truth data on material performance.
The Zeus platform is the company’s planned orbital launch complex. Auriga Space states the Zeus system is designed to enable responsive space missions with a turnaround time of one hour.
To guide its defense applications, the company appointed former Missile Defense Agency Director Lt. Gen. (Ret.) Henry “Trey” Obering III to its advisory board in August 2026.
Government contracts and venture backing
Founded in 2022, Auriga Space emerged from stealth in October 2023 with $5 million in initial funding. The company subsequently raised an additional $6 million in a seed round led by OTB Ventures in July 2025.
The startup has also secured multiple defense contracts to advance its technology. In August 2024, AFWERX and SpaceWERX awarded Auriga Space a $1.25 million Direct-to-Phase II Small Business Innovation Research (SBIR) contract. This was followed by a Phase 1 Small Business Technology Transfer (STTR) contract from the Missile Defense Agency on January 7, 2026.
AirPro News analysis
We view the successful field test of the Hermes system as a critical proof of concept for mobile electromagnetic launch technology. The aerospace and defense sectors are currently facing significant constraints within the solid rocket motor industrial base. By eliminating the need for onboard propellant during the initial launch phase, Auriga Space’s technology offers a scalable, repeatable alternative. If the company can successfully scale this technology from the 10-foot Hermes container to the proposed Zeus orbital launch complex, it could substantially lower launch costs and alleviate supply chain bottlenecks for both tactical defense systems and dedicated space access.
